There aren’t many worse things you can do as an employee than driving drunk while at work, a fact that extends to Zamboni drivers.

A 34-year-old man was arrested in Apple Valley, Minn., after police were called to the local rink to investigate what was some erratic Zamboni driving, the Minneapolis Star Tribune reports. The part-time employee was having problems getting the Zamboni off the ice after his sloppy driving while on the ice.

While Dornstreich was working with a referee, a parent came over to say that the attendant was “weaving all over, slurring his words.”

Witnesses noticed that the job, which usually takes about 10 minutes, took him 25 minutes to complete because he attempted to fix missed spots.

Dornstreich warned the referee, who was in charge of moving the nets off the ice, to stay clear of the driver. The coach then made sure that everybody stayed away from the glass during the joyride. When the man finished his sloppy work, parents had to go onto the ice to “scrape off the rough parts” so the team could practice.

The man also reportedly stumbled and smelled of booze and was arrested by authorities after he failed field sobriety tests. The investigation is ongoing and he’s yet to be charged, but state records state the man in question has been convicted of drunk driving on three other occasions, according to the Star Tribune.
